7 My invention relates to new and useful improvements in an adjustablearticle of furniture and more particularly to an article of furniturehaving an adjustable back andhas 15 for one of its objects to connectthe lower end of a back-frame or similar part to a body frame so thatthe upper end of said back fame can be moved into various positions andprovide means to hold it in any one of the Another object of theinvention is to adjustably connect one frame to another and providemeans, spring operated in one direction, to hold the adjustable frame indifferent 15 positions, the partsbeing solfashioned and assembled thatthe frames may be upholstered. 1

A further object of the invention is to provide the adjustable backframe of an article 2 of furniture with a pair of spring actuated boltsfor holding'said back frame in several adjusted positions, said boltsbeing operable manually against the action of the springs K by a set oflevers connected to a spring actuated rod slidably mounted in the backframe.

With these and otherends in view, this in-' vention consists in thedetails of construction ELDd'COIIlblIlaUOII of elements hereinafter setforth and then specifically designated by the claims. V I

' In order that those skilled in the art to which this inventionappertains may understand how to make and use the same, I will Idescribe its construction in detail, referring by numerals to theaccompanying-drawing forming a part of this application, ,in which jFig. 1 'is' a perspective view of a chair I frame with the upholsteryremoved illustrating an application of my invention:

Fig. 2 is an inner face viewof one of the rearuprights of the body frametoshow a keeper for one of the bolts.

Fig. 3 is an enlarged end view of one of the bolts and its case. w

' Fig. 4 is a longitudinal section thereof with the bolt andispring inelevation.

In carrying out my invention as herein embodied, 5 represents a chairwhich will serve 50 to illustrate an application of myinventionincluding a body frame 6 and an adjustable back frame 7. The body framemay be of any desirable formation and preferably such that it can beupholstered. Said body frame inso as to be upholstered and includes apair of side members 9 which are naturally properly braced or joined tocross pieces. This back frame is swingingly mounted at or near its lowerend on a rod or axle 10 which passes through the sides 9 and has itsends mounted in the uprights 8 of the body frame, and if founddesirable,a bearing hole 11 may be provided in a keeper plate 12 forsaid ends of the rod or axle, which keeper plate is mounted on theinsideface of each upright 8 and may be provided with keeper holes-13 for thebolts to be presently described. Of course it will be understood thatthe keeper plates may be eliminated and the holes 13 and 11 formeddirectly in the uprights 8.

An operating rod leis slidably mounted in the sides 9 of the back frameat a suitable position above the upper ends of the uprights 8 so thatsaid uprights will not interfere with the proper operation or adjustmentof the backframe. In other words, the operating rod 14 must be highenough so as not to contact with any part of ,the'body'frame, especiallythe uprights 8 during adjustment of the backframe and said operating rodprojects across the space between the two sides 9 of the back frame andone or both ends of said operating rod 'extends outside of the back.frame so as to be readily gripped and manip ulated by a person desiringto adjust the back frame, and the outside extending end or ends may eachbe provided with a knob 15.

While it will be obvious from the later description that said operatingrod does not have to be spring actuated in one direction,

' yet I prefer that it be so and I therefore pro-' vide a casing 16similar to that shownin Figs. 3 and 4, which may be mounted in either orboth of the sides 9 of the back frame with" the casings 16 embedded inthe side members-9 and the ears or flanges 30 secured to the outercasing, and the other end-ashoulder 23on the bolt which will thusnormally forcesaid bolt faces of said'side members-with the operatingrod passing therethrough, and a spring 7 hand side of Figure 1 housed inthe casing and engaginga'shoulder formed-0n the operating rod,as themovable spring actuated bolt 20. The bolt '20. is. mounted'in a casing16 similar to the ones described 1 in vconnection with the I operatingrod with a spring 21 coiledfthereabout and having one end engaging ashoulder 22 in the 7 toward the contiguous: upright 8 and cause saidbolt to register with one of the keeper holes 13 whenever properlyaligned therewith. I i To the operating rod 14 adjacent the other side 9of the back frame is pivoted one end of i a short lever 24 as at 25which lever is pivoted intermediateits ends to a bracket 26 secured tothe insideface of said other side 9, and the inner or lower end 'of saidshort lever is conpartswill be invisible except for oneor both nected bya link 27 with the upper or outer end ofa second short lever 28, thelatter being also pivotedintermediate its ends to'a bracket 29 mountedonthe inside surface of said other side 9 of the backframe. The inner orlower end of the second short lever 28 ispivotally v j ends of theuprights for slmultaneously actuconnectedto another springactuated bolt20 similarinall respects to-thefirst mentioned one since in bothinstances the bolts mustbe.

urgedoutward by the springs'for registration with keeper holes in theinside surface of the pr h s 8-v I Whenever the invention illustratedherein isused onzorjwith an upholstered article of furniture practicallyall of the operating projecting endsfof theoperating rod and the knob orknobs thereon.

When it -is desired to adjust the back frame to some positionother thanshown in s Fig, '1, the operating rod is'manually actuated toward;'theleft hand side of F ig. 1, which, through the combination of levers,

will withdraw the spring actuated bolts from,

the "uppermost keeper holes and therefore said back frame maybeswungba'ckward,

outward or downward, until the spring actuat ed. bolts are moved into"alignment with "one of the other keeper holes 13 in eachbody 7 frameupright, and at such time,-the operating rod may be released and thesprings acting on said operatingrod and bolts will move the ,latter intothe" aligned keeper holes er holes. r

whereby the back will be properly supported. Of course I do not wish tobe limited. to

the exact details of construction as-herein shown, as these may bevaried within the limits of the appended claims without departing from'the spirit of my invention.

Having thus'fully described my invention, what I claim as new and usefulis:-.
